TOOL HANDLE.

Specification of Letters Patent.

Patented Aug. 15 1922.

Application filed January 31, 1921, Serial No. 441,250.

Milwaukee, in the county of Milwaukee and State of Wisconsln, have invented new and useful Improvements in Tool Handles, of which the following is a description, reference being had to the accompanying drawings which are a part of this specification.

This invention relates to certain new and useful improvements in tool handles of that type in which the tools, such as files or the like, have their shanks engaged therein to provide convenient means for the manipulation of the tool.

At the present time, the most common form of tool handle of this character is in the form of a wooden grip having a metal ring tightly fitted on one end which is drilled and the tool shank forced into the drilled opening. This type of handle is costly in that the handle easily splits and in a short period of time is useless.

Hence with the above and other objections in mind, this invention has for one of its objects to provide a metal tool handle so designed that tools of various sizes may be accommodated and so constructed that one handle will last substantially indefinitely.

Another object of this invention is to provide a tool handle of the class described which is preferably cast in one piece of aluminum or any other suitable light material and has means within one end thereof whereby a tool shank may be driven therein to have a snug engagement.

A further object of this invention is to provide a tool handle of the class described in which means are provided'whereby a tool may be readily and quickly removed from the handle.

lVith the above and other objects in view which will appear as the description pro-- ceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which Figure 1 is a side view of a handle embodying my invention illustrating a tool as =5 inserted therein; and

Figure 2 is a sectional'view taken through the handle on the line 22 of Figure 1.

My improved handle is preferably cast of metal in one piece and has the ends thereof apertured, as at 5 and 6, and is provided, adjacent the apertured end 5, with a partition 7 which has an aperture 8 in alinement with the aperture 5. The aperture 8 is preferably of slightly smaller diameter than the aperture 5 so that whenthe shank 9 of a tool 10 is inserted therein, the tapered sides thereof will, when driven in, have a snug and firm engagement with the walls of the handle surrounding said openings.

In the event that the diflference in the diameters of the openings 5 and 8 does not properly correspond with the taper of the shank 9, the tool may be driven into the handle and the shank thereof will cut away sufficient of the opening that is too small to permit the equally tight engagement of the tool shank with the portions of the handle surrounding both of said openings. The openings 5 and 8 being in spaced relation provide means for preventing the rocking or wobbling of the tool when once firmly engaged therein, and in the event that it should be desired to remove the tool 10, the same may be easily and quickly done by the insertion of a rod through the opening 6 to tap the inner end of the tool shank, as will be readily obvious.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an article of this char acter appertains that I provide a tool handle which is capable of receiving tools of various sizes, which will possess extremely durable characteristics and which may be produced in quantities at a comparatively low cost. It will be appreciated that the handle will be made in various sizes for diflerent uses but at the same time one handle is capable of use with various sizes of tools.

What I claim as my invention is:

1. A device of the class described, consisting of a hollow one piece metal tool han dle having an opening in one end thereof through which the rectangular in cross seetion tapered end of a tool is insertable, and a. partition within the handle spaced from the end having said opening, said partition having a smaller opening in register With saidfirst mentioned opening, whereby the tool end maybe driven into said openings to have the corner edges of the tapered end have a snu Wedging fit with the partition and the end Wall of thehandle.

2.1 handle for a tool having a tapered shank of rectangular form in cross section, consisting of a tubular'one piece metal han- V dle member having a medial inner partition With an openingof less diameter than the opening through the adjacent end of the handle to 'wedgingly engage a the corner edges of the tapered shank of the tool at spaced points.

3'. A handle or a tool having a'tapered shank of rectangular form in cross section, consisting of an integral tubular metal handle member formed of aluminum and having a medial inner partition near one end with an opening of less diameter than the opening through the adjacent end of the handle, both the partition and the handle end engaging the corner edges of the tapered shank of the tool and forming spar-ed Wedging engagement therewith.

'In testimony whereof, I aflix my signature. a
